Proportional Pressure Reducing Relieving Valve

A customer wanted to improve the performance of an off-highway vehicle by replacing the component that controlled the main stage of a hydraulic valve. Designed as a continuously variable, normally open valve, this proportional valve operated over various pressure ranges to optimize controllability.

Typical Applications

Off-highway hydraulics

Auxiliary/PTO control

Turbo charger control

Variable valve timing

Transmission valves

Shift-by-wire control

Industrial controls

Oil pump controls
